IMPROVEMENT IN CANS.

Specification forming part of Letters Patent No. 177,902, dated May 23,1876; application filed September 3, 1875.

To an whom it may concern:

Be it known that I, ARTHUR R. WALLER,

- of the city, county and State of New York,

tear of the cans.

The nature of my improvement will be readily understood by reference tothe accompanying drawings, in which Figure 1 represents a plan view of aportion of a tin cut ready to be employed in manufacturing parts of cansaccording to my invention. Fig. 2 represents the periphery or sides ofone of my improved cans laid out flat; and Fig. 3, a section of thesame. Fig. 4 shows a perspective view of one of my improved canscomplete.

Similar letters of reference are employed to indicate correspondingparts wherever they occur.

According to my invention 1 take a sheet of soft tin or other suitablemetal, which I cut into strips a, as shown by Fig. l. I then take one ofthe said strips a and swage or solder the same on the side ofa sheet, b,ofthe proper size to form, when joined with a strip, a, the

side or periphery Bot a can, A, as shown by Fig.2. The combined sheet,Figs. 2 and 3, having been thus formed, I then attach the top 0 andbottom D in the ordinary manner,

leaving the opening E to be closed subsequently.

It will be seen readily that by forming the sides or periphery B of acan with a strip of soft metal, a, applied, as shown, in such mannerthat the said strip a shall. form a continuous portion of the width ofthe sideor periphcry, and having, when the can is fully completed (asshown by Fig. 4) a ring, E, of soft metal around the can A, that greateconomy is efi'ected in the manufacture of cans of this description,and, in addition, by inserting the point of a knife in the ring E andrunning it round the can, the end of the said can can' be very readilyopened.

1 am aware that annular portions of soft metal have been inserted in theends of cans for the purpose of facilitating the opening of such cans,but in this case great waste is effected in the manufacture. Asrepresented by the dotted lines in Fig. 1, it will be seen that out ofthe same sized sheet of metal, according to my invention, I can obtainthe necessary material for the soft portion of eight cans. According tothe process of manufacture wherein circular disks of metal are insertedinto the ends of the cans only three such disks can be obtained.

1 am also aware that metal cans have been constructed with a strip ofsoft metal soldered to the Wall of the can and afterward to the cover ofthe same, there being a thickness of harder metal inside the soft metal.

Having thus described my invention, I would have it understood that Ilay no claim to a ring or plate of soft metal inserted in the top or endof a metal can, as I am aware the same has been previously used; but

What I do claim, and desire to secure by Letters Patent, is-

As a new article of manufacture, a metal can constructed with a strip orrim of soft metal, E, inserted between the ends or top and bottom of thecan, and solely forming a continuous portion of the periphery or sides Bthereof, substantially as shown and described.
